Jsqrcode

jsqrcode este o bibliotecă JavaScript pentru decodarea codurilor QR într-un browser web. Funcționează ca un scaner și decodor de coduri QR capabil să extragă text și date codificate din diverse surse vizuale.

Biblioteca suportă extragerea datelor din imagini statice prin URL-uri și data URL-uri, precum și din elemente canvas. Oferă, de asemenea, capabilități de scanare în timp real prin procesarea fluxurilor video live de la camera dispozitivului prin API-ul media devices.

Procesarea sa internă acoperă detectarea modelelor, eșantionarea pixelilor și decodarea matricei binare. Utilizează corecția de erori Reed-Solomon pentru a recupera datele lipsă sau deteriorate din bitstream-ul decodat.

Features

  • QR Codes - Provides comprehensive capabilities for decoding QR codes from image URLs, data URLs, and canvas elements.
  • Camera QR Code Scanners - Detects and decodes QR codes in real time using a live video stream from the device camera.
  • JavaScript QR Decoders - A JavaScript library for decoding QR codes from images, data URLs, and live camera streams.
  • QR Code Scanning - Enables QR code scanning directly within a web browser without requiring native mobile applications.
  • Webcam Frame Captures - Captures sequential images from a live webcam stream for real-time QR scanning.
  • Visual Data Extraction - Converts visual QR code patterns into usable digital data within a web browser environment.
  • Error Correction Codes - Uses Reed-Solomon error correction to recover missing or damaged data from the decoded bitstream.
  • QR Pattern Detection - Locates the three corner squares of a QR code to determine orientation and scale.
  • Binary Matrix Decoders - Converts pixel intensity levels into a binary grid of modules for data extraction.
  • Pixel Color Sampling - Extracts raw RGBA data from canvas elements to process pixel values for pattern recognition.

    jsQR is a JavaScript library for locating and decoding QR codes directly within a browser or Node.js environment. It functions as a client-side scanner and decoder that extracts text and data from images using pixel arrays, removing the need for server-side processing. The library provides tools for QR code localization to identify the exact coordinates of corners and alignment patterns within a larger image. It uses image pattern recognition to isolate the QR code and extract its encoded content. Its internal operations cover binarization-based thresholding, geometric pattern localization,

    QRCoder is a native C# library for generating and rendering QR codes from text and data payloads. It provides a dependency-free implementation of the QR code standard for the .NET ecosystem, handling the full process from data encoding to visual output. The library includes tools for customizing QR codes through the adjustment of colors, error correction levels, and the embedding of custom logos. It also supports standardized payload formatting for specific data types such as WiFi credentials, contact cards, and payment systems. The rendering engine outputs QR codes into multiple formats, in

    EFQRCode is a Swift library for generating, styling, and scanning QR codes across iOS, macOS, watchOS, tvOS, and visionOS. It functions as a toolkit for creating both static and animated QR codes and extracting encoded text from one or multiple codes within a single image. The library enables visual branding through the integration of watermarks, icons, and animated sequences. It supports multi-format export, allowing generated codes to be saved as static images, lossless PDFs, animated GIFs, or video files. The toolkit covers high-level functional areas including QR code generation, image-b
